项目摘要

The demand for safe and clean drinking water has rapidly increased, due to population growth and global industrialization. Furthermore, the limited freshwater sources are polluted by receiving large amounts of wastewater generated by municipalities and various types of industries. Thus, advanced wastewater purification technologies are highly desirable for environmental protection. Aerobic membrane bioreactor (AeMBR), a relatively new and advanced technology, has been widely used for both municipal and industrial wastewater treatment globally but has to compete with the conventional biological wastewater treatment technologies, such as activated sludge processes, for the market. The evolution of the AeMBR technology calls for further studies to improve process efficiency, energy consumption, process design, and optimization of process operation. The proposed study aims to improve and optimize AeMBR process design and operation by studying the biological and membrane behaviours of AeMBR under process conditions and using machine learning (ML) for advanced membrane fouling control. It is anticipated that the outcomes of this study will fill the knowledge gaps of AeMBR under short solids retention time and hydraulic retention time and develop modelling tools to improve process design and operation. The success of this study will develop a new AeMBR design manual, expand the market of AeMBR technologies, and develop the next generation of AeMBR technologies, and promote the Canadian wastewater purification technologies for applications all over the world.

由于人口增长和全球，对安全干净的饮用水的需求迅速增加工业化。此外，有限的淡水来源受到大量的污染由市政当局和各种类型的行业产生的废水。因此，先进的废水净化对于环境保护，技术非常需要。有氧膜生物反应器（AEMBR），A 相对较新的技术，已广泛用于市政和工业废水全球治疗，但必须与常规生物废水处理竞争市场的技术，例如激活的污泥工艺。 AEMBR技术调用的演变进一步的研究以提高过程效率，能耗，过程设计和优化过程操作。拟议的研究旨在改善和优化AEMBR流程设计和操作在过程条件下研究AEMBR的生物和膜行为并使用机器用于高级膜结垢控制的学习（ML）。预计这项研究的结果将填补 AEMBR在短固体保留时间和液压保留时间下的知识差距并发展建模工具以改善过程设计和操作。这项研究的成功将发展一个新的 AEMBR设计手册，扩展Aembr技术的市场，并发展下一代 AEMBR技术，并推广加拿大废水净化技术用于应用程序世界。
